Cutting workstation

ABSTRACT

A cutting workstation which includes a cutter mounted on an arm type configuration. The arm configuration is slidably moveable relative to a divided work piece support table, the cutter moveable there between. Further, the cutter is capable of elevating the arm either above or below the worktable. Not only is the arm capable of being lengthened and shortened, but also it is also of capable of rotation producing a variety of miter cuts. The arm is also capable of rotating to a vertical axis to produce a chop cut motion. The bifurcated table or work piece support is capable of being rotated through a number of degrees relative to the cutter also producing mitered or angled cuts. The bifurcated worktable is also capable of being elevated above or below or at the level of the cutter. The cutter, if in the form of a circular cutter blade, is preferably provided with the conventional pivotal spring-loaded blade guard. If the cutter is in the form of a router or shaper bit, it should be preferably provided with a pivotal spring-loaded or fixed dent guard. An embodiment of the invention will now be described with reference to the drawings.

BACKGROUND

The present invention relates to a materials cutting device. Moreparticularly, a wood cutting device used in the capacity of a shaper orsaw. The device performs numerous types of cuts, such as chop cuts,miter cuts, crosscuts and rip cuts, both from above and below the workpiece support table.

Various saws currently available are used for performing a variety ofoperations and several saws combine certain functions. See U.S. Pat.Nos. 5,797,307; 5,768,967; 4,211,134 and 3,465,793. However, in thevarious permutations, there appears to be a fixed relationship betweenthe cutting blade and the work surface or table or the cutting blade isdesigned to move primarily relative to the fixed position of the worksurface. There is presently no saw known in which the position of thework surface, and consequently, the work piece, and the cutting devicecan adopt many and varied positions relative to one another. Thisresults in much of the prior art being utilized for limited functionssuch as cutting as opposed to routing, or chop cutting as opposed to ripcutting. Portability functions are not integral in much of the priorart.

Currently existing saws uniformly exhibit narrow cutter enclosures orinserts. Because of this limitation, these saws are less capable ofperforming cuts on irregularly shaped work pieces. Cutter inserts arenon adjustable and when changing cutters, inserts must also be changedor removed. Adjustments in blade angle and height in the prior art isusually accomplished by a sometimes laborious and time-consuming handcranking. In those existing saws where the motor is close to the cutter,moving the cutter also requires moving a bulky motor past the workpiece.

OBJECTS AND ADVANTAGES

An object of this invention is to provide multiple cutting functions andcomplete versatility regarding the way the cutter can act upon aworkpiece and complete versatility regarding the angle the workpiece canadopt, through the adjustability of the machine, in relation to thecutter. Because of its mobile, yet substantial base and carriage, thebenefits of many different cutting functions may be easily transportedto the job site yet have the stability of the stationary machines seenin a standard workshop. The device is stable on its own frame withoutthe necessity of a separate work platform.

Another objective of the present invention is to provide a broad rangeof configurations of the work surface and the cutting apparatus relativeto one another. Just as the cutter may be positioned above or below thework surface and consequently above or below the work piece, the worksurface is also adjustable and may be raised either lower or higher inrelationship to the cutter. In addition, the work surface may be tiltedfrom the horizontal resulting in miter cuts of varying degrees beingperformed on the work piece. The cutter arm and consequently the cuttermay be moved back and forth in relation to the work surface and, inaddition, is rotatable through 360 degrees along its long axis. Thiscoupled with the fact the work surface may also be tilted, results in amiter cuts through a large range of angles. Thus, this device allows anunlimited number of positional permutations to be achieved.

The miter gauge and the variable opening between the left and right worksurface components allow the work piece to be placed and supported inlarge number of positions. A corollary to the ability to place the workpiece in a number of positions is the ability for the invention toaccommodate work pieces with a large variety of shapes. Because of thisfeature, the device has application in a production settings where itmight be more efficient to pre-assemble components and then subject thecomponent to certain milling operations. The pre-assembled componentscould have irregular shapes this device could accommodate. The distancebetween the left and right work surfaces have an added advantage ofaccommodating cutters of various sizes and configurations.

The cutter can also be rotated to and fixed in a position parallel tothe worktable allowing the work piece to be laid flat on the worksurface. This would allow the routing or cutting of the edges of thework piece. The cutting arm can be moved downward into the work piecefacilitating a chop cut. The arm, if kept on the horizontal, can bemoved through the work piece by riding forward and backward on railsallowing the blade to move horizontally through the workpiece for crosscuts. The table elevation assembly associated with the work surface isalso capable of adjusting its position relative to the work piece fromboth above and below allowing a depth of cut adjustment. The broad rangeof adjustability of the device components along with the ability toposition the work piece in a number of ways provides maximum flexibilityand utility.

In addition to the adjustability of the device, another object of theinvention is to allow the operation and adjustments quickly, safely andefficiently from a front-mounted control handle. Table tilt and heightare controlled though mechanisms that initially allow quick adjustmentwithout hand cranking. However, after the quick adjustment, this deviceallows hand cranking to achieve more precise settings if needed. Thesequick adjust mechanisms utilize threaded drives which benefit from amechanism to both lubricate and clean the threads of dust and debris asadjustments are made thereby avoiding wear and extending the life of theadjustment components.

Utilization of a direct shaft drive connecting the motor to the cutterallows better power transfer, requires less space than standard beltdrives and dramatically reduces vibration associated with belt drivemechanisms. Further, using a shaft allows the motor to be positionedalong the same axis of the shaft itself avoiding using additional gears.Using a shaft with the motor position along its axis also allows theshaft to be rotated 360 degrees allowing the cutter to adopt almost anyorientation relative to the work piece.

The combination rip face and miter gauge is integral in maintaining workpiece positioning yet allowing a variety of work piece positions to beachieved.

These and other objects of the invention will be apparent to thoseskilled in is art from the following detailed description of thepreferred embodiment of the invention.

Leg assembly 13 is pivotally mounted to second legmounting strut 17 and first leg mounting strut 17 a. Second leg mountingstrut 17 exhibits second leg mounting plate 13 d, which further exhibitsecond leg mounting plate detent 13 f. Similarly, first leg mountingstrut 17 a exhibits first leg mounting plate 13 a which also in turnexhibits first leg mounting plate detent 13 c. The ends of axialcomponent 13 b are disposed within the second leg mounting plate detent13 f and the first leg mounting plate detent 13 c allowing the entireleg assembly 13 to pivot there within. First leg mounting strut 17 a ismounted to upper frame second longitudinal member 19 d while second legmounting strut 17 is mounted to upper frame first longitudinal member 19c. FIG. 1D illustrates the cutter arm assembly 249 which carries thepower source, power transmission means to the cutter and the cutteritself is contained. Cutter arm assembly 249 is mounted to cutter armpositioning assembly 251 which is illustrated in FIG. 1G. Cutter armpositioning assembly 251 allows the cutter arm assembly 249 to beraised, lowered, moved forward and rearward, and moved in a choppingaction. Cutter arm positioning assembly 251 along with cutter armassembly 249 is mounted to workstation base frame 253 a which isillustrated in FIG. 1H. The cutter arm positioning assembly 251 is movedforward and rearward, along the workstation base frame 253 a. FIG. 1Fillustrates worksurface positioning assembly 252 which is adjustablymounted to the workstation base frame 253 a. Work surface platform 250is adjustably mounted to the worksurface positioning assembly 252. Theworksurface positioning assembly 252 allows the work surface platform250 to be raised and lowered relative to the cutter arm assembly 249.The work surface platform 250 is itself adjustable to any number ofangles, in conjunction with the worksurface positioning assembly 252 andin relation to the cutter arm assembly 250.

Turning now to the components of cutter arm assembly 250. As shown inFIG. 28A, the motor 200 is mounted actually with the shaft housing 256.The motor mounting plate 190 is fixed to the motor 200 by means of aplurality of motor mounting plate bolts 198. FIG. 28B shows the motormounting plate 190 having a motor mounting plate central aperture 201 ainto which the externally threaded clutch and primary shaft enclosurefirst end 201 is disposed. Once disposed, the clutch and primary shaftenclosure first end is secured by means of motor mounting plate setscrew 190 a. The opposing end of the cutter arm, the clutch and primaryshaft enclosure second end 217 c is internally threaded. The externallythreaded gear case neck 217 a is disposed within the internally threadedclutch and primary shaft enclosure second end 217 c. The gear case 217is equipped with a gear case nipple 193 for lubrication purposes. FIG.28A further shows the motor shaft 208 dispose through the center of themotor mounting plate 190, extending into the center of shaft housing256. FIG. 28C illustrates the relationship between the first clutchplate 211 and the second clutch plate 212. The first annular sleeve 202is attached to the first clutch disk 211 a. This attachment isstrengthened by a plurality of triangular first clutch plate supports216 b mounted at pre-determined intervals around the first annularsleeve. The first annular sleeve 202 exhibits the first annular sleeveslot 202 a. The motor shaft 208 is disposed within the first annularsleeve. The motor shaft 208 exhibits a corresponding longitudinal motorshaft slot 216 first key 216 a is of such dimensions that it may besimultaneously disposed within first annular sleeve slot 202 a andlongitudinal motor shaft slot 216, thereby locking motor shaft 208 andfirst annular sleeve 202 in rotation. First key 216 a is secured withfirst clutch plate set screw 204 b. Clutch plate alignment pin 195 a isinserted through first clutch disk central opening 211 d until it comesinto contact with the first annular sleeve internal stop 215 c. Thisallows a pre-determined length of the clutch plate alignment pin 195 ato protrude from first clutch disk central opening 211 d. Second clutchplate 212 is attached to second annular sleeve, and again isstrengthened with the plurality of second clutch disk supports 213 a anda configuration substantially similar to that scene with the firstclutch plate 211. The clutch plate alignment pin 195 a is disposedthrough the second clutch disk central opening 212 e and extends intothe second annular sleeve and will rest against any second annularsleeve internal stop 215 b. When the motor shaft 208 is in its fixedposition within the first annular sleeve 202, the distance between theend of the motor shaft 208 and the first annular sleeve internal stop215 c is somewhat longer than the length of the clutch plate alignmentpin 195 a. This will allow the first clutch disk 211 a and the secondclutch disk 212 b with its clutch plate friction inducing surface 212 awill allow full contact with one another. Cutter drive shaft spring 209is disposed within the second annular sleeve on the side of the secondannular sleeve internal stop 215 b opposed to the location of the clutchplate alignment pin 195 a. The end of primary shaft 195 is narrowed toform a positioning rod 195 g which is disposed a short distance withincutter drive shaft spring 209. Longitudinal primary shaft slot 195 b inprimary shaft 195 receives second key 195 c which is also receivedwithin second annular sleeve slot 215 a. Second key 195 c is secured bysecond clutch plate set screw 204 a and prevents the primary shaft 195from rotating within the second annular sleeve. This configurationallows lateral movement of the second annular sleeve 215, along theprimary shaft thereby allowing cutter drive shaft spring 209 to exert aforce against second clutch plate 212, which in turn allows pressure tobe exerted against first clutch plate 211. Primary shaft first bearing203 is pressed onto primary shaft 195. Turning again to FIG. 28A, it isseen that when the primary shaft 195 is disposed within clutch andprimary shaft enclosure 199, primary shaft first bearing 203 is pressedinto and rests in clutch enclosure bearing seats 199 a. The primaryshaft 195 extends along and within the clutch and primary shaftenclosure through gear case neck 217 a and into gear case 217. A primaryshaft second bearing 203 a is pressed onto primary shaft 195 in such aposition and it is pressed into and seats into another clutch enclosurebearing seat 199 a. The first beveled gear 210 is mounted on the end ofprimary shaft 195 that extends within gear case 217. A secondary shaft206 is disposed within the gear case 217 at right angles to the axis ofthe primary shaft 195. A secondary shaft first bearing 194 is pressedonto the end of secondary shaft 206. Secondary shaft first bearing 194is then pressed into and rests within one of the gear case bearing seat194 b. The second beveled gear 205 is mounted on the secondary shaft insuch a position as to communicate with first beveled gear 210 at the endof primary shaft 195. A secondary shaft second bearing 194 a is pressedonto secondary shaft 206 and extends through gear case 217 terminatingat arbor 109 b. The arbor 109 b then receives the cutter 69, which issecured by a nut. Clutch and primary shaft enclosure 199 has a clutchaccess opening 196 a covered by cover plate 196. The clutch and primaryshaft enclosure has two internally threaded apertures corresponding totwo apertures in cover plate 196 and is held in place by bolts. It willbe noted that cutter drive assembly 195 d, shaft housing 256, and clutchacess opening 196 a are respectively and separately shown in FIG. 28D,FIG. 28E and FIG. 28F.

An alternative embodiment of the machine capable of routing and shapingis illustrated in FIG. 29A. This illustrates secondary shaft 206equipped with routing chuck 207. Mounted in routing chuck 207 isstraight router bit 207 a . As the work piece is moved past straightrouter bit 207 a, a milling operation is produced on work piece W.Although straight router bit 207 a is illustrated, router or shaper bitsand other configurations may be utilized such as cove bit 207 c. FIG.29C illustrates a configuration where the clutch and primary shaftenclosure 199 is rotating allowing production of an angled groove inwork piece W. Returning to FIG. 29A, cutter stabilization clamp 245 isseen in place. Cutter stabilization clamp 245 mutually communicates withclutch and primary shaft enclosure 199 and first work surface 61 andsecond work surface 61 a. FIG. 29B shows the major components of thecutter stabilization clamp. The major components being arm clamp 246which communicates with clutch and primary shaft enclosure 199, tableclamp 248, which communicates with first work surface 61 and second worksurface 61 a.

Arm clamp shaft 246 f is then adjusted to the proper heightsuch that clutch and primary shaft enclosure 199 is cradled in thecutter arm anvil 246 e. When clamping bracket adjusting handle 246 h isrotated, the threaded end that comes into contact with the arm clampshaft causing the clamping jaw to clamp the clutch and primary shaftenclosure 199 between itself and the cutter arm anvil 246 e. FIGS. 2Aand 2B show the relative position of the work surface platform 250 andcutter 69 when the work surface positioning assembly is extended as inFIG. 2A and contracted as in FIG. 2B. As seen in FIG. 2A, the first worksurface 61 is attached to the left horizontal member 39 to a hingeassembly 44. Hinge assembly 44 is composed of a series of work surfacehinge components 44 a, which communicate with a series of lefthorizontal member hinge components 44 b by means of a horizontal memberhinge pin 56 extending through the hinge components and held in place byhorizontal hinge pin snap ring 60. Left horizontal member 39 ispivotally attached to left adjuster strut. While left horizontal member39 is again pivotally attached to the left table elevation lever 28.Left adjuster strut 40 is attached to outer left bracket member 29 andinner left bracket member 29 a. The left table elevation lever 28 issimilarly pivotally attached to outer left bracket member 29 and innerleft bracket member 29 a. The left table elevation lever 28 extendsbelow and between the outer left bracket member 29 and inner leftbracket member 29 a and is curved toward and extends beyond the front ofthe work surface positioning assembly 252 and terminates at left handleattachment end 28 a. As shown in FIG. 8, the left handle attachment end28 a of the left table elevation lever 28 is attached to handle bar 64,which extends horizontally to the right side of the work surfacepositioning assembly 252 and attaches to right handle attachment end 28b of the corresponding right table elevation lever 28 c. Also shown inFIG. 8, the right table elevation lever 28 c extends between and ispivotally attached to the inner right bracket member 29 b and outerright bracket member 29 c. The right table elevation lever 28 c thenextends upward to be attached to the right horizontal member 39 a. Theright horizontal member 39 a communicates with right adjuster strut 39d, which in turn communicates and is pivotally mounted between the innerright bracket member 29 b and the outer right bracket member 29 c. FIG.2B further shows left fine adjuster strut 24 which communicates with theouter left bracket member 29 and inner left bracket member 29 a. FIG. 3illustrates the left fine adjuster strut 24. A first vertical strutcomponent 24 a and a second vertical strut component 24 b extend upwardfrom adjuster strut base 24 c. Left adjuster strut 40, which is mountedbetween outer left bracket member 29 and inner left bracket member 29 ais also mounted between first vertical strut component 24 a and secondvertical strut component 24 b. Adjuster strut pivoting fastener 33 isinserted through second vertical strut component aperture 33 a, thenthrough outer left bracket member 29, through left adjuster strut 40,through inner left bracket member 29 a and finally through firstvertical strut component aperture 33 d.

The vertical face 24 eof adjuster strut base 24 c contain a plurality of lateral adjustapertures 24 f, which correspond to base support circular apertures 20a. Adjuster strip bolts 49 inserted through lateral adjust apertures 24f, through base support circular apertures 20 a and are fixed in aposition utilizing adjuster strip nuts 49 a. Due to the oblong nature oflateral adjust apertures 24 f, the left fine adjuster strut 24 may bemoved laterally along base support 20 allowing the lateral strutadjustment and allowing adjustment of the work surface positioningassembly 252 as a whole. Horizontal face 24 d also contains internallythreaded vertical adjust apertures. Externally threaded verticaladjustment bolts 25 are inserted through vertical adjustment lock nuts26 and then through vertical adjust apertures 50. Vertical adjustmentbolt 25 then makes contact with base support 20 by turning the verticaladjustment bolt 25 against base support 20, vertical adjustment of theleft fine adjuster strut 24 is accomplished. After vertical adjustmentis accomplished, vertical adjust lock nut 26 is tightened againsthorizontal face 24 whereby holding vertical adjustment bolt 25 in place.

FIG. 9B illustrates the position of work surface height adjuster 11 inrelation to the height adjuster frame 307. FIG. 9C illustrates theposition of the work surface angle adjuster 9 also in relations toheight adjuster frame 307. FIG. 9A shows the work surface angel adjuster9 operating on the worksurface surface platform 250.

Left fine adjuster strut 24 is mounted to base support 20 extendingacross the work station base frame 253 a. The right fine adjuster strut24 g is constructed similar to the left fine adjuster strut 24 andcommunicates a similar fashion with base support 20 and the outer rightbracket member 29 c and the inner right bracket member 29 b. FIG. 8shows the face frame 57, which is part of the work station base frame253 a. The face frame 57 communicates and is permanently mounted to boththe inner right bracket member 29 b and the inner left bracket member 29a and the inner right bracket member 29 b and the outer right bracketmember 29 c. Also shown in FIG. 8 is the face frame 57, the upper leftcorner of which is truncated to allow the work surface positioningassembly 250 to tilt as is illustrated in FIG. 8. Returning to FIG. 2B,it can been seen when handle bar 64 is raised, the table elevationassembly 41 collapses and the work surface positioning assembly 250 islowered, allowing the left horizontal member 39 and the correspondingright horizontal member 39 a to rest on outer left bracket member 29 andinner left bracket member 29 a and rest on inner right bracket member 29b and outer right bracket member 29 c as seen in FIG. 2A. Conversely,when the handle bar 64 is fully lowered, the work surface positioningassembly 250 is at its maximum height. FIG. 2B also shows the worksurface height adjuster 11 which is attached to face frame 57. Turningnow to FIG. 7, it is seen that work surface height adjuster 11 isattached to face frame 57 by means of height mounting first strut 30 andheight mounting second strut 30 a. FIG. 5 shows the work surface heightadjuster 11 in detail. A height adjuster central rod 32 exhibits twocircumferential grooves 48 a at the height adjuster central rod firstend 32 f. FIG. 6A shows the height adjuster universal block 59 equippedwith a bore through which height adjuster central rod 32 is inserted.The height adjuster universal block is positioned on height adjustercentral rod 32 between circumferential grooves 48 a and central rod snaprings 48 are inserted into the circumferential grooves 48 a fixing theposition of height adjuster universal block 59 on height adjustercentral rod 32. Turning now to FIG. 4, it can be seen that the heightadjuster universal block 59 is pivotally mounted within hinge box 58.Hinge box 58 is attached to the left horizontal member 39. This providesthe work surface height adjuster with its attachment to the work surfaceplatform 250. Returning to FIG. 5, it is seen that height adjustercentral rod 32 is disposed through height adjuster first cap 34, firstcap sealing washer 32 d and first cap dust wiping washer 32 e. Thecentral rod is then disposed through height adjuster annular section 35which has a height adjuster annular section first end 35 b and a heightadjuster annular section second end 35 a, both of which are externallythreaded. The internally threaded height adjuster first cap is thenexposed over the height adjuster annular section first end 35 b securingfirst cap sealing washer 32 d and first cap dust wiping washer 32 e. Theexternally threaded height adjuster annular section second end 35 a isthen disposed within height adjuster second cap wherein second capceiling washer 32 a and second cap dust wiping washer 32 b are retained.Turning again to FIG. 7, it shows height adjuster annular section 35 inplace through height quick adjust block 37. FIG. 7 also shows a view ofheight adjuster first cap 34 with first cap internally threaded aperture34 f. The threads of the first cap internally threaded aperture 34 fcommunicate with external threads of height adjuster central rod secondend 32 g. It is this communication, which allows fine adjustingmovements of central rod 32. The externally threaded height adjustercentral rod second end 32 g is attached to cranking handle 27. Returningnow to FIG. 7, it further shows the height quick adjust block 37. Theheight quick adjust block 37 exhibits an internally threaded top surfaceaperture 36 b disposed within internally threaded top surface aperture36 b is pad 36 a and externally threaded height adjust block set handle36. The height adjust block set handle 36 may be deployed to secureheight adjuster annular section 35 in a given position within heightquick adjust block 37. Height quick adjust block 37 exhibits heightquick adjust block smooth bore aperture 37 a and opposing height quickadjust block smooth bore aperture 37 b and are designed to receivepartially threaded pins 31. Height mounting first strut 30 is attachedto height quick adjust block 37 by the partially threaded pins 31 whichare inserted through lock washer 31 a then through internally threadedfirst strut aperture 31 b. Height mounting second strut 30 a is attachedto height quick adjust block in a similar fashion allowing the heightquick adjust block to pivot between height mounting first strut 30 andheight mounting second strut 30 a. FIG. 4 illustrates the attachment ofthe height adjuster central rod 32 to the left horizontal member 39 bythe insertion of the height adjuster universal block 59 into hinge box58 by aligning the internally threaded hinge box 51 and 51 b with theheight adjuster universal block smooth bores 59 a and 59 b. The externalthreads of first threaded pin 52 and second threaded pin 52 a aredisposed within the internally threaded hinge box apertures 51 and 51 ballowing the pins to engage the height adjuster universal block 59 lessallowing the height adjuster universal block 59 to pivot within hingebox. Hinge box 58 is fixed by hinge box mounting plate 58 a which isfixed to the left horizontal member 39. Returning now to FIG. 2B, it canbe seen that quick adjustment of the work surface platform is achievedby loosening height adjust block set handle 36 allowing height adjusterannular section 35 to slip within height quick adjust block 37. Uponachieving the approximate position, height adjust block set handle 36 istightened. Further refinement of height may be achieved by rotating theheight adjuster central rod 32 by turning cranking handle 27. FIG. 8shows the work surface angle adjuster 9. It is constructed substantiallysimilar to the work surface height adjuster 11. The work surface angleadjust is mounted to the right horizontal member 39 a. FIG. 6Billustrates the height adjuster universal mounting bracket 240. Theangle adjuster universal block is substantially similar to the heightadjuster universal block 59. The angle adjuster universal block 58 b isinserted between angle block mounting bracket first strut 240 d andangle block mounting bracket second strut 240 f and is secured by angleblock partially threaded pin 240 a and angle block partially threadedpin 240 b. The pins are then inserted within angle strut internallythreaded apertures 240 c allowing angle adjuster universal block 58 b topivot therein. Returning to FIG. 8, it illustrates the work surfaceangle adjuster being attached to the angle adjuster mount 241 b which isin turn attached to the right horizontal member 39 a.

Now turning to FIG. 1O, which shows the mechanism quickly adjusting thework surface to predetermined angles. Work surface connector 46 exhibitsa plurality of work surface connector stops 80 positioned partiallyaround exterior surface. FIG. 15B best illustrates the relationship ofthe work surface connector 46 to the first work surface 61 and thesecond work surface 61 a. The work surface connector 46 is attached tofirst side panel 61 e of the first work surface 61 and the left sidepanel 61 h of the second work surface 61 a. Now returning to FIG. 10, itis seen that work surface connector stops 80 are positioned such thatwhen engaged by rocker assembly stop arm 79, the work surfaces are fixedat certain predetermined angles such as 22.5 degrees, 45 degrees, 67.5degrees, etc. Rocker assembly stop arm 79 is inserted through slidebracket 81. FIG. 11 shows that slide bracket 81 contains slide bracketslot 79 a which exhibits overhanging retention flanges 81 a, whichcapture the rocker assembly stop arm. The rocker assembly stop arm 79contains a stop arm aperture 79 c through which stop arm threaded knob78 passes. Internally threaded stop arm retention washer 79 b restsbelow rocker assembly stop arm 79. When stop arm threaded knob 78 istightened, the stop arm retention washer 79 b is drawn tight against therocker assembly stop arm which in turn is drawn tight against theretention flanges thereby locking the rocker assembly stop arm 79 inplace. By adjusting the position of the rocker assembly stop arm 79within slide bracket 81, small variances in the angle of the worksurfaces can be achieved and the angle of the work surface can best becalibrated to predetermined angles. Returning to FIG. 10, it is seenthat slide bracket 81 is mounted to rod 88. Rocker bracket 85, which ismounted to the right horizontal member 39 a, contains two correspondingflanges, rocker bracket first flange 85 a and rocker bracket secondflange 85 b. Rocker bracket first flange 85 a and rocker bracket secondflange 85 b contain two corresponding apertures through which rod 88extends. Rod 88 rotates freely within those apertures. Slide bracket 81is mounted on that portion of rod 88 resting within rocker bracket 85.Right horizontal member 39 aexhibits a cutout 79 c allowing the rockerassembly stop arm to assume a proper position in relation to the worksurface connector stop 80. Externally threaded sleeve 87 is receivedwithin right horizontal member threaded aperture 39 b in addition tobeing held within the corresponding apertures of the rocker bracketfirst flange 85 a and rocker bracket second flange 85 b, rod 88 ismounted within threaded sleeve 87 allowing free rotation. Rocker handle82 attached to rod 88 allows rotation of rod 88 and consequent movementof the rocker assembly stop arm toward or away from work surfaceconnector stops 80. The threaded sleeve 87 extends through angled flange39 c and through slotted brace 67. Slotted brace washer 70 a is placedover threaded sleeve 87 and slotted brace knob 70 is mounted thereon.When slotted brace knob 70 is tightened, it secures slotted brace 67 inposition. Slotted brace 67 is pivotally attached to slotted bracebracket 67 a. Slotted brace bracket 67 a is mounted to front rail 42.Front rail 42 is, in turn, mounted to the second work surface 61 a atthe second work surface assembly front panel 61 f. The ability to secureslotted brace 67 by means of slotted brace knob 70 allows the worksurface to be positioned between predetermined angles established by thework surface connector stops 80. FIG. 12 illustrates the relationshipbetween the first work surface assembly 300, the cutter 69, and thesecond work surface assembly 300 a. Within the first work surfaceassembly 300 is first work surface 61. Similarly within the second worksurface assembly 300 a is second work surface 61 a. First work surface61 and second work surface 61 a are separated by a space, the width ofwhich is modifiable by the activation of the first inserted adjustingmeans 301 and the second inserted adjusting means 301 a. When theinserted adjusting means are activated, the distance between the firstwork surface insert 76 and the second work surface insert 76 a is eithernarrowed or expanded. The cutter 69 mounted to the cutter arm 90 rideson the cutter arm positioning assembly 251 forward and between the firstwork surface insert 76 and the second work surface insert 76 a therebyperforming a cross cut on the work piece. Further, the cutter armpositioning assembly 251 may be locked in any position, completelyrearward, completely forward or any variation inbetween. At any fixedposition, a chop cut can be performed or a rip cut can be performed bymoving the work piece into the cutter. In addition, if the shape of thepiece to be milled warrants, the cut can be initiated in a chop cutfashion cutting through or to any desired depth and then the cut may betransformed into the cross cut or rip cut. FIG. 13 illustrates thecutter arm lock 107. Cutter arm 90 is capable of 360 degree rotation andcontains a plurality of clutch and primary shaft enclosure smooth bores116 around its circumference at predetermined positions. Central rodknob 94 is fixedly mounted to cutter arm lock central rod first end 103a. Cutter arm lock central rod second end 103 b extends through clutchand primary shaft enclosure smooth bores 116 thereby locking cutter arm90 at a predetermined position which in turn determines the angle of thecutter 69. The travel of the cutter arm lock central rod 103 through theclutch and primary shaft enclosure smooth bores 116 is limited bycentral rod stop 105. Positions and consequent angles between thoseestablished by the clutch and primary shaft enclosure smooth bores 116are achieved by the use of the brake 92 a of the cutter arm lock shoe92. The brake 92 a having a concave face which communicates with theconvex exterior of cutter arm 90. Cutter arm lock shoe 92 exhibits anexternally threaded cutter arm lock shoe neck 104. Cutter arm lockcentral rod 103 extends through shoe setting neck aperture 104 a whichitself extends through brake 92 a. The shoe setting neck aperture 104 ais large enough to accommodate central rod stop 105 as well as shoesetting spring 102 which when in position over the cutter arm lockcentral rod 103 and within cutter arm lock shoe 92, rests againstcentral rod stop 105. The shoe setting cap 95 exhibits an internallythreaded shoe setting cap aperture and also large enough to accommodateshoe setting spring 102. The shoe setting cap exhibits a shoe settingcap first end 95 b and a shoe setting cap second end 95 c. Shoe settingcap first end 95 b exhibits a shoe setting cap central bore 95 d. Shoesetting cap tube 106 is disposed over shoe setting cap central bore 95d. Shoe setting cap tube 106 exhibits shoe setting tube snap ringgrooves 106 a designed to receive shoe setting tube snap rings 115. Thecutter arm lock central rod extends through shoe setting cap tube 106.Shoe setting cap handle 93 is mounted to shoe setting cap tube 106 andoperates to rotate shoe setting cap 95 allowing it to be disposed overthe cutter arm lock shoe neck 104. This compresses shoe setting spring102 between shoe setting cap 95 and central rod stop 105. When centralrod knob 94 is pulled, cutter arm lock central rod 103 is withdrawn fromthe clutch and primary shaft enclosure smooth bores 116 releasing thecutter arm 90 and allowing the rotation. If the cutter arm lock centralrod second end 103 b is outside an aperture and riding on the surface ofcutter arm 90, shoe setting spring 102 exerts pressure on central rodstop 105 which transmits the pressure to the cutter arm lock central rod103 such that when the cutter arm lock central rod second end 103 bencounters a succeeding clutch and primary shaft enclosures smooth bores116, cutter arm lock central rod 103 is automatically seated. FIG. 14shows an alternative embodiment of the cutter arm assembly 249 as wellas the cutter arm lock 107. Turning first to the cutter arm lockmechanism 107, it is seen that collar 114 is composed of a collar firstleg 114 a, collar second leg 114 b, and a transverse collar section 114joining the two legs. Collar first leg 114 a exhibits collar first bore114 d, while collar second leg exhibits collar second bore 114 e. Cutterarm 90 is disposed through collar first bore 114 d and collar secondbore 114 e. The transverse collar section 114 c also exhibits centralangular transverse collar section aperture 114 f through which shoesetting cap tube 106 is disposed. Shoe setting cap tube 106 is held inposition by shoe setting tube snap rings 115. When the cutter arm lock107 is rotated clockwise onto the cutter arm lock shoe neck 104, itcauses cutter arm lock shoe 92 to pull away from cutter arm 90. Thisallows the cutter arm to be repositioned. When the cutter arm lock 107is rotated counter clockwise, cutter arm lock shoe 92 and brake 92 a,frictionally engages cutter arm 90 allowing cutter arm to be positionedat any angle in addition to the angle predetermined by the location ofclutch and primary shaft enclosures smooth bores 116. Collar positioningtabs 91 respectively contain collar positioning tab openings 91 bthrough which collar positioning tab set screws 91 a attach collarpositioning tabs 91 to cutter arm 90. The collar positioning tabopenings are elongated and oriented toward opposing corner of the collarpositioning tabs 91. This allows the position of the collar 114 to beadjusted to facilitate the seating of cutter arm lock central rod 103within clutch and primary shaft enclosure smooth bores 116.

Returning to the alternative embodiment of the cutter arm and cutterdrive mechanism. Here, in contrast to the preferred embodiment, themotor 101 is mounted perpendicularly to the longitudinal axis of cutterarm 90 on motor mount 100. Motor mount 100 also exhibits a motor mountannular shaft 101 a extending perpendicularly from the plane of motormount 100. Mounted to cutter arm 90 is plate 96. Plate 96 contains aplate annular aperture 101 b within which motor mount annular shaft 101a is disposed such that motor mount 100 may rotate. Plate set screw 96 ais disposed within plate set screw aperture 96 b and plate 96 such thatthe set screw communicates with motor mount annular shaft 101 a, hockingplate 96, and consequently cutter arm 90 in a fixed position. Belt drivemotor 101 is attached to it. First pulley 98 that communicates withdrive belt 97, which in turn communicates with the second pulley 109,located at bearing closure 89. Bearing closure 89 is to tubular in shapeand mounted to cutter arm extension 77. Cutter arm extension 77 istubular in nature and is disposed of within tubular cutter arm 90 and isheld in a particular position by 90 a. Further cutter arm extension 77may be rotated within cutter arm 90 allowing precise calibration of theangle of the cutter 69 in relation to the clutch and primary shaftenclosure smooth bores 116. Bearing sets 113 are mounted at each end oftubular bearing and closure 89. Axle 108 is disposed through bearingsets 113 and disposed within bearing enclosure 89 and is mountedperpendicularly on and to cutter arm extension 77. Second pulley 109 ismounted to axle first end 108 a with arbor 109 b mounted to axles secondend. FIG. 15D is a perspective view of portions of the first worksurface assembly 300 and second work surface assembly 300 a. A portionof first work surface assembly 300 is designated as first work surface61. Not only are we extending from first work surface 61 is first worksurface front panel 305, the first work surface outer panel 304, firstwork surface rear panel 303, first work surface inner panel 302. Incombination with first work surface top panel 306 creates a rectangularbox-like configuration with an open bottom comprising the first worksurface 61. On the interior edge of first work surface top panel 306,the first work surface front panel 305, the first work surface rearpanel 303, the first work surface top panel 306, and the first worksurface inner panel 302 are modified to form a top panel ledge 306 d.Turning now to FIG. 15A, it is seen that the first work surface insert76, has first work surface insert horizontal component 76 c and a firstwork surface insert vertical component 76 b. In its retracted position,the first work surface insert horizontal component 76 c rests on the toppanel ledge 306 d such that the first work surface 61 is flush with thefirst work surface insert horizontal component 76 c forming a contiguousplane. Further, in its retracted position, the first work surface insertvertical component 76 b rests flush with first work surface inner panel302. The configuration of the second work surface assembly 300 a issubstantially similar to that described above for the first work surfaceassembly 300. Turning now to FIG. 15B, it can be seen that the insertadjusting rods 74 communicate with the interior surface of the firstwork surface insert vertical component 76 b. The insert adjusting rods74 extend through insert adjusting rod apertures 75 a in first worksurface inner panel 302. The insert adjusting rod 74 are furtherdisposed through adjusting rod compression springs 75 and thence throughinternally threaded spring adjuster seat 76 f, which form apertures infirst work surface outer panel 304. Spring adjuster 76 i is thenthreaded into spring adjuster seat 76 f. FIG. 15C illustrates thisrelationship in a magnified view. This is repeated for both insertadjusting rods 74. The insert adjusting rods 74 has the exit throughspring adjuster seat 76 f mutually communicate with first adjustinghandle bracket 71. As can be seen in FIG. 15D, midway along firstadjusting handle bracket 71 are two lever mounting brackets 72 d. Levermounting bracket pin 73 extends through apertures in lever mountingbrackets 72 d and the corresponding aperture in the adjuster handle 72allowing adjuster handle 72 to pivot. Adjuster handle 72 has a curvedface portion 72 b. An alternative embodiment of adjuster handle 72 wouldexhibit a facet face 72 c as can be clearly seen in FIG. 15B. Returningnow to FIG. 15D, we see that when handle portion 72 a rests against thehandle bracket, the work surface insert is fully extended. Resting atits maximum distance from the work surface. When handle portion 72 a isrotated away from the work surface, then the work piece support abutsthe work surface. Returning to FIG. 15B, it can be seen that whenadjuster handle 72 is rotated away from the first work surface 61adjusting rod compression springs 75 are compressed between springadjuster 76 i and the first work surface insert. This provides tensionbetween the curved face portion 72 b of the adjuster handle 72 and thefirst work surface outer panel 304, allowing adjuster handle 72 toremain in the set position. Further assisting the adjuster handle toremain in set position, it is groove 74 f.

Thus, it can be seen that if both the first work surface insert 76 andthe second work surface insert 76 a are fully extended, it provides thenarrowest path for cutter 69 to traverse. If both work surface insertsare retracted, it provides the widest path for the cutter 69 allowingwork pieces of regular dimensions to be partially positioned below thework surface and still be operated upon. FIG. 15A also shows front rail42. Front rail 42 has a series of front rail perforations 74 b on frontrail front face 42 a. Corresponding rear face perforations 76 u of asmaller diameter occur in the opposing face of front rail 42 allowingfront rail screws 42 b to be inserted through front rail perforations 74b, then through rear rail perforations 76 u, thence through spaceraperture 47 a, then into work surface aperture 74 g. In this way frontrail 42 is mounted to the front panels of first work surface 61 andsecond work surface 61 a. Front rail 42 extends across and beyond thewidth of the work surfaces. Now turning again to FIG. 15B, at the rearof first work surface 61 and second work surface 61 a, second rear rail43 and first rear rail 43 a are respectively mounted in a similarfashion as front rail 42. However, first rear rail 43 a and second rearrail 43 are mounted such that the cutter 69 can pass between them.Further, it can be seen that second lateral work surface extension 47 fis comprised of first bar 47 d and first bar first tube 47 c and firstbar second tube 47 e. First bar first tube 47 c is inserted withinsecond rear rail 43 and first bar second tube is inserted in front rail44 f. The first lateral work surface extension is similar constructedand mounted opposite to the second lateral work surface extension 47 f.

FIG. 15B also serves to illustrate the configuration of attachment ofwork surface connector 46. Work surface connector 46 contains four worksurface connector perforations 75 g through which insert adjusting rods74 pass. Work surface connector 46 is secured to the second work surfaceinner panel 61 h and first work surface outer panel 304. Work surfaceconnector 46 exhibits work surface connector first strut 46 a and worksurface connector second strut 46 b which extends to the rear walls oftheir respective work surfaces. Hinge mounting brackets 76 q is fixedlyattached to the first work surface and extends parallel to first worksurface outer panel until it meets work surface connector strut 46 a andis mounted thereto. Mounted to the hinge mounting brackets 76 q is hingeassembly 44 which consists of a plurality of hinges.

FIG. 16A shows the components of the cutter work station that allow theelevation of the cutter arm 90 and allows chop cutting and isconsequently termed the elevation and chop cut carriage 112 a. Carriagelock housing 117 communicates with base hinge 138. Base hinge 138exhibits horizontal base end component 138 a and vertical base hingecomponent 145. Both joined by base hinge pin 139. As illustrated in FIG.16A, carriage lower platform 137 is composed of carriage lower platformbase 137 c, carriage lower platform first side wall 137 a and carriagelower platform second side wall 137 d. Turning to FIG. 16B, first catch121 is pivotally mounted to carriage lower platform first side wall 137a and carriage lower platform second side wall 137 d, and extends belowand through catch opening 137 e (visible on FIG. 16A) such that whencarriage lower platform is horizontal, first catch 121 communicates andinterlocks with second catch 129 mounted on carriage lock housing top154 a (visible in FIG. 20B). When first catch 121 and second catch 129interlock, cutter arm 90 is fixed in a horizontal position allowingcross cut and rip operations. The horizontal base hinge component 138 ais mounted to carriage lock housing and communication with tensionspring 144, which in turn communicates with the carriage lock housing117. Tension spring 144 operates on the rear edge of carriage lockhousing 117 through its attachment with the horizontal base hingecomponent 138 a allowing the forward edge of the carriage lower platformto elevate. FIG. 18A illustrates the catch activating mechanism. Firstcatch 121 exhibits first catch aperture 121 f. First catch pin 121 cextends through an aperture in carriage lower platform first side wall137 a and then through second catch spacer 121 h and out through acorresponding aperture and carriage lower platform second side wall 137d. First catch pin 121 c is held in position by the first catch pin head121 k and first catch pin snap ring mounted outside carriage lowerplatform second side wall 137 d and seated in first pin annular groove121 d. Leaf spring 121 g is mounted between half moon tabs 121 l, whichprotrude from carriage lower platform base 137 c. Leaf spring 121 g isheld to the carriage lower platform base 137 c at leaf spring bolt 121i. Pass through leaf spring aperture 121 m and a corresponding aperturein carriage bolt platform base 137 c and fixed with leaf spring nut 121j. Leaf spring 121 g is mounted substantially in the center of thecarriage lower platform base 137 c so it corresponds with the positionof first catch 121 and communicates therewith. Leaf spring 121 g is alsopositioned to apply continuous pressure to catch 121. Turning now toFIG. 16B, it can be seen that second catch 129 is positioned in suchmatter that when carriage lower platform 137 is lowered toward the uppersurface of carriage lock housing 117, the first catch curved face 121 nof first catch 121 contacts the second catch curved face 129 a of secondcatch 129 such that first catch 121 depresses leaf spring 121 g untilfirst catch tooth 121 o of first catch 121 passes below second catchtooth 129 b of second catch 129. Leaf spring 121 g then presses on firstcatch 121 causing second catch tooth 129 b and first catch tooth 121 oto interlock. Returning to FIG. 18A, it can be seen that first catch 121is released from its interlock position with second catch 129 by meansof offset catch cam 121 a. Second catch pin 121 p extends through anaperture in carriage lower platform first side wall 137 a, then throughthird catch spacer 121 r, then through offset catch cam aperture 121 s,then through first catch spacer 121 u and out through a correspondingaperture and carriage lower platform second side wall 137 d. Secondcatch pin 121 p is held in position in a similar fashion as first catchpin 121 c. However, second catch pin 121 p is fixed to offset catch cam121 a. Further, second catch pin 121 p exhibits catch handle 121 b. Whensecond catch pin 121 p is rotated, offset catch cam 121 a communicateswith first catch 121 which in turn depresses leaf spring 121 g. Firstcatch 121 is moved away from second catch 129 causing first catch tooth121 o to disengage from second catch tooth allowing carriage lowerplatform 137 to rise.

Carriage lower platform first side wall 137 a and carriage lowerplatform second side wall 137 d exhibit a plurality of pivotally mountedcarriage struts 112 c, which also pivotally communicating with andlending support to carriage upper platform 128. Turning now to FIG. 16A,it is seen that the serrated arm 130 extends downward and rearwardbetween first offset cam support 142 and second offset cam support 142c. The serrated arm 130 communicates with serrated arm tension spring131, which in turn communicates with the carriage lower platform base137 c. When the serrated arm 130 is drawn rearward, carriage upperplatform 128 pivots rearward on pivotally mounted carriage struts 112 ccausing carriage upper platform 128 and consequently the cutter arm 90to lower. At the same time the tension in the serrated arm tensionspring 131 is increased. Turning now to FIG. 17, it is seen that thefirst offset cam support 142 and the second offset cam support 142 c aremounted to carriage lower platform first sidewal 137 a and carriagelower platform second sidewall 137 d, and extend upward and rearward.First offset cam support 142 and second offset cam support 142 c exhibitcorresponding apertures, through cam lobe axle 132 a extends. Thus, camlobe axle 132 a creates a pivotal mounting for offset cam lobe 140.Offset cam lobe 140 is fixedly attached to cam lobe axle 132 a andmounted between first offset cam support 142 and second offset camsupport 142 c. One end of cam lobe axle 132 a exhibits cam lobe axlehandle 132. When cam lobe axle handle 132 is activated, offset cam lobe140 rotates within first offset cam support 142 and second offset camsupport 142 c. Each offset cam support exhibits an additional pair ofcorresponding apertures through which elongated tabs 141 a of carriageelevation locking shoe 141 extend allowing carriage elevation lockingshoe 141 to be pivotally mounted between the offset cam supports.Serrated arm catch 143 is mounted between carriage lower platform firstside wall 137 a and carriage lower platform second side wall 137 d. Inthis configuration, when cam lobe axle handle is activated, offset camlobe 140 is rotated into contact with carriage elevation locking shoe141 which in turn contacts serrated arm 130 forcing serrations 130 a tocommunicate with serrated arm catch 143. Friction between offset camlobe 140, carriage elevation locking shoe 141 and the upper surface ofthe serrated arm 130 will assist offset cam lobe 140 to maintain itsposition. The pressure exerted by offset cam lobe 140 causes serratedarm catch 143 to remain in position between serrations 130 a, lockingthe carriage upper platform 128 in a temporarily fixed position thuscounteracting the tension in serrated arm tension spring 131. Placingserrated arm catch 143 between the various serrations 130 a determinesthe height of carriage upper platform 128 and consequently the height ofcutter arm 90.

FIG. 19A illustrates the carriage lock assembly 149 in its relationshipto first rail 253 g. Further shown in 19A is the carriage locking offsetcam lobe 135 disposed within carriage lock cam housing 149 a. FIG. 21illustrates an end view of first rail 253 g. First rail 253 g has afirst rail lower component 84 a and a first rail upper component 84 band their parallel configuration. First rail lower component 84 aexhibits first rail lower component lip 84 c while first rail uppercomponent 84 b exhibits first rail upper component lip 84 d. First raillower component 84 a and first rail upper component 84 b exhibit aplurality of first real spacers 155, which appear periodically along theentire length of the rails and separate first rail lower component 84 afrom first rail upper component 84 b. This separation is designed toallow the fall through of cutting dust, keeping the rails clear andsmoothly operating. The rails are disposed at an inward angle relativeto the carriage lock housing 117. FIG. 21 shows that carriage wheel 146is disposed between the first rail lower component 84 a and the firstrail upper component 84 b. The carriage wheels 146 are disposed at aninward angle relative to carriage lock housing 117, substantially thesame as the angle at which the rails are disposed.

Carriage wheel 146 communicates with carriage wheel axle 146 a. Carriagewheel 146 rides on first rail lower component lip 84 c. The first railupper component lip 84 d is angled towards carriage wheel 146 to such adegree that the extended lip rests above carriage wheel edge 146 c. thisconfiguration is substantially similar for second rail 253 h. Thecomponent lips of the rails and their position above the carriage wheelsrocks the plurality of carriage wheels in their position below the upperrail components and the lower rail components. Carriage wheel axle 146is disposed within sleeve bracket 153 and communicates with wheelmounting bracket 156 and is attached to carriage lock housing left sidewall 154 c. Two wheels are thus attached to carriage lock housing leftside wall 154 c and two wheels are attached to carriage lock housingright side wall 154 d in a similar fashion. Turning to FIG. 20B, it canbe seen that carriage lock housing 117 is substantially in the shape ofrectangular box having carriage lock housing top 154 a, carriage lockhousing left side wall 154 c, carriage lock housing right side wall 154d, carriage lock housing front 154 e and carriage lock housing back 154f. Carriage lock housing front 154 e contains three apertures. Left railfront aperture 154 g has a corresponding and opposed left rail backaperture 154 h. Right rail front aperture 154 a in carriage lock housingfront also has a corresponding and opposed right rail back aperture 154k. Four apertures allow first rail 253 g and second rail 253 h to passthrough carriage lock housing 117. The first rail 253 g and second rail253 h are disposed between work station base first transverse railsupport 253 c and work station base second transverse rail support 253f. The carriage lock housing with its plurality on internally mountedwheels is thus allowed to traverse the length of the rails. This allowsthe cutter arm positioning assembly to move to and fro. Carriage lockhousing front 154 e also exhibits front rod aperture 154 i through whichcontrol rod 124 is disposed. It should be noted that in accordance withFIG. 20B, carriage lock cam housing 149 a is mounted to the interior ofcarriage lock housing front 154 e. Turning again to FIG.19A, it is shownthat carriage lock cam housing 149 a exhibits opposing side wallsspecifically first cam housing side wall 149 b and second cam housingside wall 149 c as well as opposing top and bottom, specifically camhousing top 149 d and cam housing bottom 149 e. At first cam housingside wall 149 b and second cam housing side wall 149 c containcorresponding apertures, first side wall cam aperture 149 f and secondside wall cam aperture 149 g. FIG. 20 illustrates cam sleeve 134 thatextends through first side wall cam aperture 149 f through carriagelocking offset cam lobe 135 and then through second side wall camaperture 149 g. Cam sleeve 134 rotates freely within the side wallapertures, however, it is fixed within the carriage locking offset camlobe 135 a, so that cam sleeve cam 134 rotates in conjunction withcarriage locking offset cam lobe 135. Cam sleeve 134 is annular innature with the exception that a portion of the cam is removed along theaxis resulting in cam sleeve slot 136 running the length of cam sleeve134. Carriage locking offset cam lobe 135 also exhibits cam lobe slot136 a corresponding to cam sleeve slot 136. Cam lobe slot 136 a is bestvisualized in FIG. 21. As seen in FIG. 16C, control rod 124 exhibitscontrol rod tab 124 a. Control rod tab 124 a is configured such that itswidth and its height, or in other words, the maximum distance it extendsfrom control rod 124 allows it to freely slide within cam sleeve slot136 and cam lobe slot 136 a. Then control rod 124 is drawn forward, suchthat control rod tab 124 a is disposed within cam sleeve slot 136, whencontrol rod 124 is rotated, control rod tab 124 a communicates with andin turn rotates cam sleeve 134 which in turn will rotate carriagelocking offset cam lobe 135. Returning to FIG. 19A, it will be seen thatcam housing bottom 149 e is extended to form hinge lip 152. Stop plate150 is hingeably mounted to hinge lip 152 through stop plate hinge pin148. At such time as control rod tab 124 a is disposed within cam sleeveslot 136 and cam sleeve 134 and consequently, carriage locking offsetcam lobe 135 is rotated against stop plate 150. Stop plate 150 is forcedagainst the first rail lower component 84 a thus preventing carriagelock housing 117 from moving along first rail 253 g, and second rail 253h rotating carriage locking offset cam lobe 135 away from stop plate 150releases carriage lock housing 117 for movement.

Control rod 124 is not only used to lock carriage lock housing 117 butserves two additional purposes. FIG. 16B shows chop cut activating hinge126 attached to carriage lower platform 137 through chop cut activatinghinge pin 126 a. As shown in FIG. 16C, chop cut activating hinge 126exhibits a longitudinal chop cut activating hinge slot 126 b. Whencontrol rod tab 124 a is located behind chop cut activating hinge 126 asshown in FIGS. 16B and 16C, and is rotated perpendicularly to thelongitudinal axis of the chop cut activating hinge slot, then whencontrol rod 124 is drawn forward, control rod tab 124 a engages chop cutactivating hinge 126 drawing the hinge forward and pulling carriagelower platform 137 downward which results in cutter arm 90 being pulleddownward and consequently results in the performance of a chop cut. Whencontrol rod 124 is released, tension spring 144 causes carriage lowerplatform 137 to elevate at the front. Control rod 124 may be positionedsuch that tab 124 a is clear of cam sleeve 134. At this point carriagecontrol handle 118 may be rotated down and out of the way of cuttingoperations as is illustrated in FIG. 8. FIG. 22A through FIG. 27 showthe rip fence and miter gauge 160 b. FIG. 24 illustrates the majorcomponents being adjustable base 176, arm 171, and fence 159. FIG. 26illustrates rip fence and miter gauge mounting bracket 178 attached toadjustable base 176, which is in turn is attached to base line 171. FIG.24 illustrates extension arm 160 mounted within base arm 171 with theopposing end of extension arm pivotally attached to fence 159. Returningto FIG. 26, it is seen that rip fence and miter gauge mounting bracket178 is in the form of a U-shape of such a dimension that it would slipover front rail 42. Rip fence and miter gauge mounting bracket 178exhibits mounting bracket tabs 178 b which come out above and below theopen side of rip fence and miter gauge mounting bracket 178. Tabs 178 bprevent the rip fence and miter gauge mounting bracket 178 from beingpulled off front rail 42. This arrangement allows the rip fence andmiter gauge mounting bracket 178 and consequently the rip fence andmiter gauge 160 b to slide along the length of front rail 42 keeping inmind that tabs 178 b clear both above and below front rail spacers 47.Returning to FIG. 26, it is seen that along the bottom edge of rip fenceand miter gauge mounting bracket 178 is mounted internally threadedmounting bracket bridge 170. Externally threaded bridge set screw 164 isdisposed within the internally threaded aperture of mounting bracketbridge 170. When bridge set screw 164 is rotated within the internallythreaded aperture, bridge set screw 164 makes contact with bridgepressure spring 182, which in turn makes contact with first rail 42resulting in rip fence and miter gauge mounting bracket 178 being heldin a temporarily fixed position along front rail 42. Rip fence and mitergauge mounting bracket 178 is attached to angle bracket 177, which inturn has a vertical angle bracket component 177 a and a horizontal anglebracket component 177 b. Horizontal angle bracket component 177 bcontains horizontal angle bracket internally threaded aperture 177 c.Angle bracket 177 is mounted such that horizontal angle bracketcomponent 177 b is flush with the surface of rip fence and miter gaugemounting bracket 178. Mounting bracket bolt 175 a is disposed withinsemi-circular slot 176 a within adjustable base 176. When mountingbracket bolt 175 a is rotated, in the appropriate direction, adjustablebase 176 is tightened against angle bracket 177 temporarily fixing basearm 171 in position. FIG. 24 shows two of the various positions the ripfence and miter gauge 160 b may adopt through its arc. Semi-circularslot 176 a exhibits a plurality of adjustment plate set screw seats 176c. The adjustment plate set screw seats 176 c are positioned around thesemi-circular slot 176 a in such a way that when mounting bracket bolt175 a is disposed within the adjustment plate set screw seats 176 c, ripfence and miter gauge 160 b will adopt a series of predetermined anglesrelative to front rail 42. Mounting bracket bolt 175 a may be tightenedat positions between the adjustment set plate set screw seats 176 c sothat angles between predetermined angles established by the location ofadjustment plate set screw seats 176 c may be obtained. FIG. 26 alsoillustrates that base arm 171 pivots upon arm pin 174 which mounted torip fence and miter gauge mounting bracket 178. The distal end of armpin 174 is externally threaded and the base arm 171 is retained by basearm threaded knob 173. FIG. 24 illustrates fence 159 with semi-circularfence component 159 a and straight edge component 159 b. Semi-circularfence component 159 a also exhibits fence semi-circular slot 159 c.Fence semi-circular slot 159 c is configured substantially similar tosemi-circular slot 176 a. Turning to FIG. 27, it is seen that fence 159pivots about fence pin 165. Fence pin 165 exhibits a head and anexternally threaded end that is disposed through aperture and thirdfence surface 159 g. Then through apertures in the distal extension armend 171 b, then through a corresponding and opposite aperture in secondfence surface 159 f. Allowing fence 159 to pivot on the distal extensionarm end 171 b. FIG. 27 also exhibits horizontal pin plate component 179b attached to the upper surface of extension arm 160. Vertical pin 179 cis attached to pin plate 179 b. Vertical pin 179 c is disposed throughfence semi-circular slot 159 c. Pressure bushing 183 is then disposedover vertical pin 179 c as is vertical pin spring 169, spring washer186, and internally threaded base arm threaded knob 173 a. When base armthreaded knob 173 a is tightened, vertical pin spring 169 compressesapplying pressure to pressure bushing 183, which rests at some pointwithin fence semi-circular slot 159 c or within fence component circularpressure bushing seats 185, which are configured substantially similarlyto adjustment plate set screw seats 176 a. Thereby keeping fence 159 ina predetermined position.
